Abstract (en)

The method involves transmitting, by a calling terminal, a request message for setting up a call between calling and called terminals. An alert message, indicating that the called terminal is alerted, is transmitted by the called terminal. A connection message, indicating that the called terminal is picked up, is transmitted by the called terminal. Logic audio and video channels are set up between the calling and called terminals. The channel set up is started immediately after sending the alert message and before sending the connection message. Independent claims are also included for the following: (1) a calling terminal for emitting a call setup request message (2) a called terminal for receiving a call setup request message.
